# Experimental & Discontinued Autopilots
This category is for experimental and discontinued autopilots (and autopilot "platforms") that are not supported by either the PX4 project team or by a manufacturer.
For more information about PX4 project autopilot board support levels see: px4.io/autopilots/ (opens new window).
Boards in this category must work with at least one PX4 release for a defined vehicle type. They may not be compatible with the current PX4 release, and compatibility is not maintained by the project for future releases.
The boards in this category are:
- Aerotenna OcPoC-Zynq Mini
- BeagleBone Blue
- Bitcraze Crazyflie 2.0 (Complete Vehicle)
- Raspberry Pi 2/3 Navio2
- Raspberry Pi 2/3/4 PilotPi Shield
